Remember that you don't have to write "self.field" - "field" by itself 
is fine, as long as you haven't assigned to a local variable called 
"field" within the calling method.

def field
  123
end

puts field       # 123
field = 999
puts field       # 999
puts field()     # 123
puts self.field  # 123
